Abstract
Official abstract text for this publication.
A light source system for a stereoscopic projection apparatus is provided. The light source system has a light source module, a first lens unit, a light splitting element, a color wheel module and a light integration element. The light source module provides a light beam, which is transferred by the first lens unit to the light splitting element. Then, the light beam is split by the light splitting element into a first light beam with a first bandwidth and a second light beam with a second bandwidth. The first and the second light beams are then received and transformed by the color wheel into a third light beam and a fourth light beam which are then transmitted to the light integration element. With the above arrangement, the light source system can be applied on a projection apparatus to provide a stereoscopic image.
